Surface-enhanced Raman scattering of λ -DNA
Source abstract
Abstract
By using the molecular combing method, we stretched DNA molecules with colloidal silver nanoparticles adsorbed on them. Surface-enhanced Raman scattering (SERS) spectra were recorded in this particular DNA/Ag system. We also studied SERS spectra of DNA molecules in solution. The spectra of DNA in different concentration solution show distinct differences, and we speculate that the coiling states of DNA molecules are different in different concentrations, leading to the spectral differences.
